in the cloud
one click: the provider's deploy form opens filled in, in your own account- koyeb
-
The form opens with CHANGE_ME for each value you supply: SENDGRID_API_KEY, SENDGRID_MCP_MODE, SENDGRID_MCP_RECIPIENT_ALLOWLIST, SENDGRID_MCP_WRITES_PER_HOUR, SENDGRID_MCP_MAX_RECIPIENTS, SENDGRID_MCP_AUDIT_LOG, SENDGRID_MCP_ALLOW_BCC. Fill them in before you deploy.
Clients connect to the service's https://…koyeb.app address plus /mcp.
- azure
-
A Container Apps environment with one app per server, each with HTTPS ingress and one replica. The portal asks for each value you supply as a secure parameter; the deployment's outputs list the endpoints.
